Create the file in Illustrator and select continuously rasterize.
Thank you Rick.
That sounds perfect,
I will run a test now...before briefing the artist.
Tested - I had no luck with .ai files but .eps worked perfectly.... as per Ricks tip regarding continuous rasterisation.
Did the artist make the AI file as two layers, one for the black bars and one for the white background? Did the artist work in RGB? AE doesn't like CMYK.
It was my own test file (.ai) that I made. that did not display aat all in AEFX even though I believ I made it RGB.
When I exported as .eps...it worked perfectly.
SunsequentIy I instructed the artist to supply .eps....and separate B&W layers.
